Description
If Netty/the NIO Selector reads the following message in a single read
T 127.0.0.1:8080 -> 127.0.0.1:51295 [AP]
HTTP/1.1 101 Switching Protocols.
Upgrade: websocket.
Connection: Upgrade.
Sec-WebSocket-Accept: mFFTAW8KVZebToQFZZcFVWmJh8Y=.

T 127.0.0.1:8080 -> 127.0.0.1:51295 [AP]
.21808c569-099b-4d8f-b657-c5965df40449|1391270901601
The 21808c569-099b-4d8f-b657-c5965df40449|1391270901601 won't be decoded by Netty's Decoder and will get lost. The workaround is to add a whitespace payload between the handshake's headers and the first websocket message.
